Description

As a certified reference material (CRM), 5287E3OUAV 5153-67-3 2-Nitro-1-phenylethylene Benzene, (2-nitroethenyl)-, (E)- (9CI) Styrene, beta-nitro-, (E)- 4-05-00-01352 (Beilstein Handbook Reference) BRN 1210066 (E)-(2-Nitroethenyl)benzene trans-beta-Nitrostyrene (E)-beta-Nitrostyrene UNII-5287E3OUAV 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.

5287E3OUAV 5153-67-3 2-Nitro-1-phenylethylene Benzene, (2-nitroethenyl)-, (E)- (9CI) Styrene, beta-nitro-, (E)- 4-05-00-01352 (Beilstein Handbook Reference) BRN 1210066 (E)-(2-Nitroethenyl)benzene trans-beta-Nitrostyrene (E)-beta-Nitrostyrene UNII-5287E3OUAV (CAS 5153-67-3) is a high-purity analytical reference standard with the molecular formula C8H13NO2 and a molecular weight of 155.19 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5287E3OUAV 5153-67-3 2-Nitro-1-phenylethylene Benzene, (2-nitroethenyl)-, (E)- (9CI) Styrene, beta-nitro-, (E)- 4-05-00-01352 (Beilstein Handbook Reference) BRN 1210066 (E)-(2-Nitroethenyl)benzene trans-beta-Nitrostyrene (E)-beta-Nitrostyrene UNII-5287E3OUAV is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
