Description
Formaldehyde solution 37 % is an aqueous reagent grade with a minimum content of 37 %, supplied for synthesis applications in the laboratory. The active species corresponds to empirical formula CH₂O (CAS number 50-00-0), with molar mass 30,03 g/mol, density 1,09 g/cm³, boiling range 93 to 96 °C and flash point 62 °C. EG nr. 200-001-8 identifies the substance for regulatory documentation. This supports preparative and synthetic work where a concentrated formaldehyde solution is required, and it is also relevant in histology and microscopy fixation contexts within life-science workflows. Physical data from manufacturer Carl ROTH enable straightforward integration into existing protocols and risk assessments. The solution is intended for professional laboratory use only; users should consult the accompanying safety documentation before handling. Consistent concentration and clearly stated physicochemical parameters help ensure reproducible results in synthesis and related fixation procedures.

Questions about Formaldehyde solution 37 %, min. 37 %, for synthesis, 1 l, plastic
What is this article?
Formaldehyde solution 37 %, min. 37 %, for synthesis, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
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 Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) 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.
