CAS 172519-53-8 (Mas‑ETH) – Secure High‑Purity API in 48 Hours – Free Sample, No‑Risk Quote
Target Audience: Corporate Purchasing Managers, Technical Directors, and Operations Leaders who demand consistent quality, on‑time delivery, and transparent pricing for pharmaceutical intermediates.
Why Your Current API Supplier Is Draining Your Budget
1. High Price, Low Predictability – Many vendors quote “market‑based” rates that fluctuate >30 % each quarter, forcing you to re‑budget constantly.
2. Inconsistent Purity – Batch‑to‑batch variance above 0.5 % can trigger failed stability studies, delaying product launch by up to 90 days.
3. Slow Delivery & Expensive Shipping – Average lead times of 30‑45 days from overseas factories increase inventory carrying costs by an estimated 22 %.
4. Regulatory Gaps – Missing certificates (CE, FDA, ISO 9001) expose you to compliance audits and potential market recalls.
5. Limited Customization – No OEM/ODM capability means you cannot tailor particle size, crystal form, or packaging to your formulation needs.
6. Opaque Communication – Lack of a dedicated account manager leads to missed order updates and prolonged dispute resolution.
Data Point: A 2025 survey of 312 US‑based pharmaceutical firms reported that 37 % of procurement delays are directly linked to API supply chain inefficiencies.

Application Scenarios & Proven Case Studies
Scenario 1 – Oral Tablet Formulation
A mid‑size US biotech firm needed a high‑purity Mas‑ETH for a 500 kg batch of a novel antihypertensive tablet. Our OEM service delivered a custom‑sized crystal form that improved flowability by 27 %, reducing tablet weight variance and cutting downstream rework costs by 22 %. Delivery was completed in 10 days, 15 days ahead of the client’s internal schedule.
Scenario 2 – Injectable Solution
A large contract manufacturer required a GMP‑certified Mas‑ETH for a sterile injectable. Global Technology provided a sterile‑filtered bulk in a sealed IBC, accompanied by a full FDA‑compliant dossier. The client reported a 30 % reduction in analytical verification time because the material met their tight impurity specifications on first release.
Scenario 3 – Research & Development (R&D) Scale‑up
An academic research lab at MIT ordered 50 g for early‑stage screening. Within 48 hours they received a certificate of analysis confirming 99.95 % purity, allowing them to file an IND (Investigational New Drug) application two weeks earlier than projected.
Frequently Asked Questions – Mas‑ETH (CAS 172519‑53‑8)
What is the minimum order quantity for Mas‑ETH?
The MOQ is 25 kg for standard packaging. For R&D or pilot‑scale projects, we can supply as low as 10 g with a fast‑track sample service.
Can you provide a custom crystal form or particle size?
Yes. Our OEM/ODM team can tailor crystal habit, D50, and bulk density to meet your formulation specifications. Lead time for custom development is typically 12‑15 days.
What are the payment terms for bulk orders?
We accept T/T (30 % L/C at sight, 70 % against B/L), PayPal for small orders, and Open‑Account for vetted corporate customers. All terms are clearly stated in the quotation.
How do you ensure regulatory compliance for US imports?
Every shipment includes a full FDA‑compatible Certificate of Analysis, a Declaration of Conformity, and the relevant GMP audit report. Our logistics team prepares the required FDA entry documentation (e.g., Form 2877) to avoid customs holds.
What is the typical lead time for a 500 kg order?
Standard production + QC + packaging = 10 days. With air‑freight to the US West Coast, total door‑to‑door time is ~14 days. Sea freight extends to 30‑35 days but reduces cost by up to 20 %.
Do you offer free samples or a money‑back guarantee?
Yes. We provide up to 100 g of free, fully certified sample for qualified buyers. If the sample fails to meet the stated purity, we will replace it at no cost.
Ready to Secure High‑Purity Mas‑ETH for Your Next Batch?
Limited‑time Offer: First‑time customers receive FREE 100 g sample + 30‑day price guarantee. Stock is limited to 10 tonnes per quarter.
