Does CAS 635-51-8 specify one enantiomer of Phenylsuccinic Acid?

No. Phenylsuccinic Acid contains a stereogenic center, and the CAS number is commonly used for material without a specified single-enantiomer claim. State racemic or defined stereochemical requirements and the chiral or optical test method when stereochemistry matters to the process.

Which specifications should be agreed for Phenylsuccinic Acid?

Agree identity, assay, related substances, residual starting materials, water, residual solvents, acid value, appearance and melting range. If an enriched form is required, add enantiomeric purity and configuration; state quantity, package and intended use so the offered grade can be reviewed against the correct methods.

Phenylsuccinic Acid CAS 635-51-8

Phenylsuccinic Acid , CAS 635-51-8 and EC 211-238-1 , is a phenyl-substituted dicarboxylic acid with formula C10H10O4 and molecular weight 194.18 g/mol. It contains a stereogenic center, so buyers should state whether racemic material or a defined stereochemical form is required. Commercial qualification should cover identity, assay, water, melting range, acid value, residual starting materials and other related substances rather than relying on a generic purity label.

CAS: 635-51-8
Synonyms: Phenylsuccinic acid, 2-Phenylsuccinic acid, 2-Phenylbutanedioic acid
Einecs: 211-238-1
Molecular Formula: C₁₀H₁₀O₄
Grade: Confirm identity, assay method, water or residual solvents, product-specific impurities and physical form against the current COA; no end-use grade is assumed.
Package: State required quantity and destination; confirm the current container, light or moisture protection, net weight, storage conditions and transport requirements against the current COA and SDS.

Identity and specification

Item	Verified purchasing information
Product	Phenylsuccinic Acid; 2-phenylsuccinic acid
CAS / EC	635-51-8 / 211-238-1
Formula / molecular weight	C10H10O4 / 194.18 g/mol
Critical selection point	Racemic or specified stereochemical form

Phenylsuccinic Acid is also described as 2-phenylsuccinic acid or 2-phenylbutanedioic acid. CAS 635-51-8 identifies the compound, while the requested stereochemical form must be stated separately. The formula is C10H10O4 and the molecular weight is 194.18 g/mol.

Quality controls for purchasing

Confirm identity by a suitable spectroscopic method and report assay on the agreed basis.
Set limits for water, melting range, acid value, residual aromatic starting materials and unknown related substances.
For stereoselective work, define racemic, enriched or single-enantiomer requirements and the analytical method.

Applications and grade selection

Phenylsuccinic Acid may be evaluated as a building block in fine-chemical and materials synthesis. Suitability depends on the reaction route and impurity tolerance. Process qualification should compare the proposed material under the intended coupling, resolution or derivatization conditions before approval.

Storage and handling

Keep the solid tightly closed in a dry, ventilated area away from incompatible bases, oxidizers and excessive heat. Use moisture-protective inner liners, preserve the original label and follow the current SDS for handling and waste controls.

Documentation and quotation details

A useful request for quotation states the stereochemical requirement, assay basis, water and related-substance limits, test methods, trial or bulk quantity, packaging, destination and delivery schedule. COA, SDS and available technical data should be reviewed before order confirmation.
