The compound is a versatile intermediate for pharmaceuticals, agrochemicals, dyes, and heterocyclic fine chemicals. It is commonly supplied at 98% purity or higher for pharmaceutical intermediate

Ethyl 4-bromobutyrate (CAS: 2969-81-5) is a colorless to pale yellow brominated ester. Its terminal bromide and ester groups support nucleophilic substitution, alkylation, and chain-extension reactions. The compound is a useful four-carbon ester linker in the synthesis of pharmaceuticals, agrochemicals, fragrances, and functional materials. It is supplied as a high-purity liquid for fine chemical synthesis, process

4-tert-Butylbenzyl chloride (CAS: 19692-45-6) is a colorless to yellow aromatic alkyl chloride. Its reactive benzylic chloride group makes it a useful electrophile for alkylation, etherification, and quaternization reactions. The para-tert-butyl substituent increases hydrophobicity and influences the performance of downstream fragrance, surfactant, agrochemical, and specialty chemical molecules. The product is used as a high-purity intermediate in

Methyltriphenylphosphonium bromide (CAS 2524-64-3) is a white to off-white crystalline phosphonium salt with formula C₁₉H₁₈BrP and MW 357.23. After deprotonation it forms a methylene ylide that converts aldehydes and ketones into terminal alkenes. It is a standard Wittig reagent precursor for carbon–carbon double-bond formation.

1,3-Dimethoxybenzene (CAS: 151-10-0) is a colorless aromatic ether with a sweet, earthy, nut-like odor. It is the meta isomer of dimethoxybenzene and is widely used as a versatile aromatic intermediate. Its methoxy groups direct further substitution reactions, making the compound valuable for preparing fragrances, pharmaceutical intermediates, agrochemicals, dyes, and functional materials. Commercial material is commonly

3-Carbamoylmethyl-5-methylhexanoic acid (CAS: 181289-15-6) is a white to off-white crystalline pharmaceutical intermediate. It contains both a carboxylic acid and a primary amide group, enabling controlled conversion into downstream chiral intermediates. The compound is associated with synthetic routes to pregabalin, an active pharmaceutical ingredient used for neuropathic pain and related therapeutic areas. It is supplied as

Rosuvastatin Formyl Intermediate (CAS: 147118-37-4) is a fluorinated pyrimidine aldehyde used as a synthetic building block in rosuvastatin manufacture. It carries the substituted pyrimidine core and a reactive aldehyde group that enables attachment of the statin side chain during synthesis. Commercial listings identify it as both a rosuvastatin intermediate and a formyl impurity or reference

1,4-Dimethoxybenzene (CAS: 150-78-7) is a white crystalline aromatic ether, also known as hydroquinone dimethyl ether or p-dimethoxybenzene. It is a stable aromatic building block used across specialty chemical manufacturing. With two para-oriented methoxy groups, it supports selective electrophilic substitution and is useful in the synthesis of fragrance ingredients, agrochemicals, dyes, and polymer-related intermediates. Commercial material

1-Bromooctadecane (CAS: 112-89-0) is a straight-chain C18 alkyl bromide supplied as a solid for chemical synthesis. Its terminal bromine atom provides a reactive site for nucleophilic substitution and long-chain alkylation, supporting preparation of octadecyl derivatives and specialty organic compounds. Documented applications include preparation of shortened single-walled carbon nanotubes and use as a precursor to an

Rivastigmine Tartrate (CAS: 129101-54-8) is the hydrogen tartrate, or L-tartrate, salt of rivastigmine, supplied as a white to off-white crystalline solid. It is a dual, reversible inhibitor of acetylcholinesterase and butyrylcholinesterase, enzymes that metabolize acetylcholine.
