{"product_id":"3-5-dichloro-4-hydroxybenzaldehyde-min-95-100-g-2l4c-2l4c","title":"3,5-Dichloro-4-hydroxybenzaldehyde, min. 95 %, 100 g","description":"\u003cp\u003e3,5-Dichloro-4-hydroxybenzaldehyde is a chlorinated phenolic aldehyde offered at a minimum purity of 95 %, identified by CAS number 2314-36-5 and empirical formula C₇H₄Cl₂O₂. With a molar mass of 191,01 g\/mol, this compound provides a defined aromatic scaffold for synthetic and biochemical applications. The dual chloro substitution and free phenolic hydroxyl make it a useful intermediate in the preparation of fine chemicals, ligands, and specialised organic building blocks. Supplied in a 100 g pack from manufacturer Carl ROTH, it supports multi-step synthesis, scale-up trials, and routine laboratory work that require a consistent dichloro-hydroxybenzaldehyde grade. Clear identity data and assay information facilitate documentation in research and development environments. Suitable for laboratories engaged in halogenated aromatic chemistry, phenolic aldehyde transformations, and related biochemical studies.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/nl-be\/collections\/organic-building-blocks-and-synthesis-reagents\"\u003eOrganic building blocks \u0026amp; synthesis reagents\u003c\/a\u003e, in \u003ca href=\"\/nl-be\/collections\/organic-chemicals-and-synthesis-reagents\"\u003eOrganic chemicals \u0026amp; synthesis reagents\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssay: ≥ 95 %\u003c\/li\u003e\n\u003cli\u003eColour: reported\u003c\/li\u003e\n\u003cli\u003eForm: reported\u003c\/li\u003e\n\u003cli\u003eCAS number: 2314-36-5\u003c\/li\u003e\n\u003cli\u003ePack sizes: 100 g, 250 g, 500 g, 1 kg\u003c\/li\u003e\n\u003cli\u003ePurity: min. 95 %\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₇H₄Cl₂O₂\u003c\/li\u003e\n\u003cli\u003eMolar mass: 191,01 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: +2 to +8 °C\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 12352200\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-2L4C-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMjgxMnxhcHBsaWNhdGlvbi9wZGZ8YURCa0wyaGpPUzg1TWpVME5EYzRNREl3TmpNNEwxTlFSVnBmTWt3MFExOUZUaTV3WkdZfDY0YzE3MGRhNjZjMzIwODNlN2RmOTczZDc1ZGZjZTU4MmQwOTk3OWZmZDc0YmFmYTgyYTkwMDJmYTg4ZGE5ZDQ\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-2L4C-DE-DE.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3w3ODY1MHxhcHBsaWNhdGlvbi9wZGZ8YUdWaEwyZzBZUzg1TVRrMk1UZzJNRGMxTVRZMkwxTkVRbDh5VERSRFgwUkZYMFJGTG5Ca1pnfGY1NjRjZDMzMTk2OGFkNDI3MmE0ZDljMjA5ZWQzZWU1YWE3MGU5ZTE4ZTZkODhmOGJjMTBmZWExNzVlNDNiZGM\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"100 g","offer_id":58952043069772,"sku":"2L4C.1","price":256.95,"currency_code":"EUR","in_stock":true},{"title":"250 g","offer_id":58952043102540,"sku":"2L4C.2","price":403.15,"currency_code":"EUR","in_stock":true},{"title":"500 g","offer_id":58952043135308,"sku":"2L4C.3","price":654.7,"currency_code":"EUR","in_stock":true},{"title":"1 kg","offer_id":58952043168076,"sku":"2L4C.4","price":1016.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/2L4C-1.jpg?v=1790398560","url":"https:\/\/www.luminixhealth.com\/nl-be\/products\/3-5-dichloro-4-hydroxybenzaldehyde-min-95-100-g-2l4c-2l4c","provider":"Luminix Health","version":"1.0","type":"link"}
