Description
Sodium chloride is a ROTI®Star CRM for volumetry with the empirical formula NaCl, CAS number 7647-14-5 and EG number 231-598-3. This inorganic salt has a molar mass of 58,44 g/mol, a density of 2,17 g/cm³ and a boiling point above 1450 °C. The product is supplied in an 80 g HDPE pack for laboratory volumetric use. Offered from manufacturer Carl ROTH as part of the ROTI®Star CRM range, sodium chloride is presented as a certified reference material for volumetry, supporting titre work and other volumetric procedures that call for characterised NaCl. The formula NaCl and the molar mass of 58,44 g/mol allow stoichiometric calculations when the solid is used to prepare volumetric solutions. Density 2,17 g/cm³ and boiling point >1450 °C are the listed physical properties of the material. The 80 g HDPE presentation is a practical pack size for preparing standards and for keeping a dedicated CRM portion at the bench. CAS 7647-14-5, EG number 231-598-3 and formula NaCl keep the chemical identity clear for method documentation and inventory.

Questions about Sodium chloride, ROTI®Star CRM for volumetry, 80 g
What is this article?
Sodium chloride, ROTI®Star CRM for volumetry, 80 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is ICP, AAS & ion standards. The catalogue is Lab chemicals.
Shelves beside this one are Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
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.
