Dimple Associates was founded in 1998 by Paresh Prajapati in Vadodara, Gujarat — the chemical manufacturing hub of India. From day one, the focus was singular: manufacture rare specialty chemicals that global buyers genuinely struggle to source reliably.
Nearly three decades on, that focus has built something most suppliers can't claim — consistent purity, consistent availability, and a direct relationship with the person who actually makes your chemical.
"We've been sourcing Phosphotungstic Acid from Dimple Associates for over 4 years. Purity is consistently high and documentation is always ready for international customs — a rare find."
"We needed Lithium Perchlorate in a specific grade for battery research. Paresh responded the same day, sent a sample within the week. No other supplier could match the speed or price."
"Sourced Silicotungstic Acid for fuel cell research. Exceptional purity, proper MSDS, and fast DHL dispatch. Will be ordering again next quarter without question."
