Prices vary a lot by grade (lab, USP/pharmaceutical, or food grade), form (anhydrous vs dihydrate), quantity, and supplier. Here are rough ballpark ranges in USD to help you budget. If you tell me your grade, desired quantity, and location, I can give more exact quotes.
- Citric acid (food/industrial grade, typically anhydrous or monohydrate)
- Bulk/lab: roughly $2–6 per kg
- Retail/1 kg bags: often $5–15 per kg
- Sodium citrate (trisodium citrate dihydrate, common food/industrial grade)
- Bulk/lab: roughly $6–15 per kg
- Retail: higher per kg, but often sold in 1–5 kg bags
- Potassium citrate (lab or pharmaceutical grade)
- Bulk/lab/pharma: roughly $20–60 per kg
- Retail: can be higher, depending on purity and packaging
Notes and tips:
- Expect lower per-kg prices if you buy in bulk (tens of kilograms or more) and if you’re okay with industrial or food-grade packaging.
- Forms matter: anhydrous vs dihydrate can affect price and用途.
- Typical packaging: 25 kg bags for industrial/food use; smaller sizes (100 g–1 kg) for consumer/experimental use.
- Get quotes from multiple suppliers (e.g., Sigma-Aldrich/Merck, Thermo Fisher, VWR/Fisher, local chemical distributors, or reputable online vendors) and specify grade, form, and quantity to compare apples-to-apples.
If you share your location, intended grade, exact amounts, and whether you want anhydrous or dihydrate, I can search for current price ranges from common suppliers and give you more precise figures.
