Description
Formaldehyde solution ROTIPURAN® 37 % is an analytical-grade aqueous formaldehyde offered as p.a., ACS material for laboratory fixation and related chemical applications. It corresponds to CAS number 50-00-0 with empirical formula CH₂O, a molar mass of 30,03 g/mol, a density of 1,09 g/cm³, a flash point of 62 °C and a boiling range of 93 to 96 °C. In histology and microscopy, formaldehyde solutions are established fixatives; this 37 % grade also serves broader analytical and preparative uses that specify ACS/p.a. quality. The product is Formaldehyde solution from manufacturer Carl ROTH under the ROTIPURAN® designation supports consistent performance where a defined 37 % solution is required. Identity data including EG nr. 200-001-8 facilitate traceability in quality systems. Use this reagent when a reliable, specification-backed formaldehyde solution is needed for fixation workflows and analytical chemistry.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Formaldehyde solution, ROTIPURAN® 37 %, p.a., ACS, 1 l, plastic
What is this article?
Formaldehyde solution, ROTIPURAN® 37 %, p.a., ACS, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
