Description
Thiourea is an analytical-grade reagent with a minimum purity of 99 % p.a., ACS, intended for demanding chemical and laboratory work. Identified by CAS number 62-56-6 and EG number 200-543-5, it has the empirical formula CH₄N₂S, a molar mass of 76,12 g/mol and a density of 1,405 g/cm³. The compound is Specifications from manufacturer Carl ROTH support consistent batch handling and documentation in quality-controlled environments. With its ACS and p.a. designation, this thiourea grade is suited to applications where high purity and well-defined physicochemical data are essential. Laboratories can use the stated molar mass and density directly for solution preparation, stoichiometric calculations and method validation across inorganic and organic chemistry workflows.

Questions about Thiourea, min. 99 % p.a., ACS, 100 g, plastic
What is this article?
Thiourea, min. 99 % p.a., ACS, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Microbiology lab supplies.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
