4-Chloro-3-nitrophenyl isothiocyanate CAS 127142-66-9

Description

The occurrence of 4-Chloro-3-nitrophenyl isothiocyanate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Chloro-3-nitrophenyl isothiocyanate (CAS 127142-66-9), a certified reference material (molecular formula C7H3ClN2O2S, MW 214.63 g/mol) for analytical method development and quality control.

4-Chloro-3-nitrophenyl isothiocyanate (C7H3ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Chloro-3-nitrophenyl isothiocyanate 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.
