Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 31GT1LW79B 115340-67-5 2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid 2-Butenoic acid, 3-formyl-2,4,4-trichloro-, (E)- (E)-2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid CCRIS 3770 (E)-2-Chloro-3-(dichloromethyl)-4-oxo-butenoic acid (E)-3-Formyl-2,4,4-trichloro-2-butenoic acid E-MX HSDB 7634 UNII-31GT1LW79B.

CATO supplies 31GT1LW79B 115340-67-5 2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid 2-Butenoic acid, 3-formyl-2,4,4-trichloro-, (E)- (E)-2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid CCRIS 3770 (E)-2-Chloro-3-(dichloromethyl)-4-oxo-butenoic acid (E)-3-Formyl-2,4,4-trichloro-2-butenoic acid E-MX HSDB 7634 UNII-31GT1LW79B (CAS 115340-67-5), a certified reference material (molecular formula C5H3Cl3O3, MW 217.43 g/mol) for analytical method development and quality control.

Structurally, 31GT1LW79B 115340-67-5 2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid 2-Butenoic acid, 3-formyl-2,4,4-trichloro-, (E)- (E)-2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid CCRIS 3770 (E)-2-Chloro-3-(dichloromethyl)-4-oxo-butenoic acid (E)-3-Formyl-2,4,4-trichloro-2-butenoic acid E-MX HSDB 7634 UNII-31GT1LW79B (C5H3Cl3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 217.43 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 31GT1LW79B 115340-67-5 2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid 2-Butenoic acid, 3-formyl-2,4,4-trichloro-, (E)- (E)-2-Chloro-3-(dichloromethyl)-4-oxobutenoic acid CCRIS 3770 (E)-2-Chloro-3-(dichloromethyl)-4-oxo-butenoic acid (E)-3-Formyl-2,4,4-trichloro-2-butenoic acid E-MX HSDB 7634 UNII-31GT1LW79B 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.
