Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 59897-94-8 Methyl trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate Cyclopropanecarboxylic acid, 3-(2,2-dichloroethenyl)-2,2-dimethyl-, methyl ester, (1R,3S)-rel- trans-3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, methyl ester EINECS 261-977-9.

59897-94-8 Methyl trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate Cyclopropanecarboxylic acid, 3-(2,2-dichloroethenyl)-2,2-dimethyl-, methyl ester, (1R,3S)-rel- trans-3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, methyl ester EINECS 261-977-9 (CAS 59897-94-8) is a high-purity analytical reference standard with the molecular formula C9H12Cl2O2 and a molecular weight of 223.10 g/mol.

59897-94-8 Methyl trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate Cyclopropanecarboxylic acid, 3-(2,2-dichloroethenyl)-2,2-dimethyl-, methyl ester, (1R,3S)-rel- trans-3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, methyl ester EINECS 261-977-9 (C9H12Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 59897-94-8 Methyl trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate Cyclopropanecarboxylic acid, 3-(2,2-dichloroethenyl)-2,2-dimethyl-, methyl ester, (1R,3S)-rel- trans-3-(2,2-Dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, methyl ester EINECS 261-977-9 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.
