Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including α,α＇-Dihydroxy-1,3-Diisopropylbenzene.
α,α＇-Dihydroxy-1,3-Diisopropylbenzene (CAS 1999-85-5) is a high-purity analytical reference standard with the molecular formula C12H18O2 and a molecular weight of 194.27 g/mol.
α,α＇-Dihydroxy-1,3-Diisopropylbenzene (C12H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), α,α＇-Dihydroxy-1,3-Diisopropylbenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
